<p align=center><b>Non-local memory allocation</b></p>
<p>Berkeley DB allocates memory for returning key/data pairs and statistical
information which becomes the responsibility of the application.
There are also interfaces where an application will allocate memory
which becomes the responsibility of Berkeley DB.</p>
<p>On systems in which there may be multiple library versions of the
standard allocation routines (notably Windows NT), transferring memory
between the library and the application will fail because the Berkeley DB
library allocates memory from a different heap than the application
uses to free it, or vice versa.  To avoid this problem, the
<a href="../../api_c/env_set_alloc.html">DB_ENV-&gt;set_alloc</a> and <a href="../../api_c/db_set_alloc.html">DB-&gt;set_alloc</a> methods can be used to
give Berkeley DB references to the application's allocation routines.</p>
